TECHNICAL APPROACH:

We combine our unparalleled success and in-house engineering experience of cutting energy costs across all industries with the expertise of our primary manufacturers. This allows us to develop the most effective turnkey projects with the greatest energy savings, largest reduction in greenhouse gas emissions and strongest return on investment for our customers.

All of the approaches and technologies we employ are proven, passive, IEEE and DOE recommended. Furthermore, our technologies are ENERGY STAR qualified because they are supplied by ENERGY STAR partners such as Phillips, GE, Telkonet and Intellidyne. We do not engineer, use or manufacture any unproven "black box" or "pixie dust" solutions.

All of the technologies we utilize are UL Listed and CSA Approved.

Many states and local utilities also offer generous incentives and rebates for our work.

Below are the main approaches used to passively cut energy consumption and improve the efficiency and operation of our customers' facilities:

VARIABLE DRIVES:

There are millions of motors in use in industry and offices around the world. In fact, more than 65 percent of industrial electrical energy is consumed by motors.

In many cases, motors are controlled by means of a valve that regulates the flow of fuel or a vane that controls the airflow while the speed of the motor itself remains unchanged. These and other methods, such as using two-speed motors or controlling them by switching on or off, are inefficient from an energy point of view.

Controlling motor speed via drives makes matching process demand and machine output possible thus reducing energy costs and greenhouse-gas emissions.

SMART HVAC/R CONTROLS:

Sizing of refrigeration and air conditioning systems is based upon a number of factors. When any of the design considerations are not met, the refrigeration or air conditioning system is relatively oversized for the cooling load and thus less efficient.

By applying a microcomputer-controlled device using proprietary internal algorithms, we can adjust compressor cycles to achieve the greatest efficiency and reduced electrical usage, while assuring consistent temperature levels. We reduce energy consumption by optimizing system performance through real-time "load demand" analysis and control.

We determine the "cooling demand" and "thermal characteristics" of the entire refrigeration or air conditioning system by analyzing the compressor "cycle patterns," and dynamically modify those "cycle patterns" to provide the required amount of cooling in the most efficient manner. This is accomplished in "real-time" by delaying the start of the next compressor "on" cycle by an amount determined by the "cooling demand" analysis. These new patterns also result in less frequent and more efficient compressor cycles. Our technology and approach electrically augments the existing controls, and will not cause the compressor to run unless the existing thermostat is calling for it to do so. Just as computer control has increased the gas mileage of automobiles, our system improves the electrical efficiency of refrigeration and air conditioning systems, by supplementing the antiquated on/off action of the thermostat (even a "smart" one) with the analysis and control capabilities of a computer.

Our technology works in conjunction with the existing thermostat and will not void the compressor manufacturer's warranty. An additional feature is the accepted industry practice of compressor anti- short-cycling control.

Other benefits include no programming, no seasonal adjustments, maximum year-round efficiency, fail safe operation, reduced maintenance and extended compressor life.

BUILDING AUTOMATION SYSTEMS (BAS):

Make Your Building a Smart Building

BAS is a control system comprised of a computerized, intelligent network of electronic devices, designed to monitor and control the mechanical and lighting systems in a building. BAS core functionality keeps the building climate within a specified range, provides lighting based on an occupancy schedule, and monitors system performance and device failures. BAS functionality significantly and cost effectively reduces building energy and maintenance costs when directly compared to a non-controlled building.

BAS can reduce overall energy consumption 5% to 30% or more depending on the age, condition and complexity of the building.

ELECTRONICALLY COMMUTATED MOTORS (ECM):

ECM’s are ultra high efficiency programmable brushless DC motors which utilize permanent magnet rotors and built-in inverters.

Typical permanent split capacitor (PSC) motors with SCR speed control are extremely inefficient (typically 12% to 45%) due to the PSC motor speed being turned down.

ECM motors on the other hand maintain high efficiency of 65% to 72% at all speeds

eCube:

By simulating food and beverage thermal qualities and automatically relaying this information to the thermostat

• Cooling cycles are reduced 50% or more; saving energy, lowering wear and tear, reducing emissions and ensuring better food safety.
• 10% to 30% average savings are attained

Most importantly the technology is NSF Approved

LIGHTING CONTROLS (SINE WAVE MODIFICATION):

Currently, greater efficiency in lighting systems typically comes from retrofitting out of date systems with higher efficiency electronic ballast fluorescent or HID lighting systems. Although this lighting is more efficient than incandescent lighting it is also true that neither fluorescent nor HID lighting is maximally efficient when connected to standard, sinusoidal waveform AC power.

To increase efficiency we utilize the principle of wave-form modification. We reduce RMS power to the lighting fixtures and reduce the amount of time the sine wave is being applied. Peak voltage remains intact allowing the fixtures to "think" they are receiving the same power with little or no discernable change in light levels.

In addition, bundled with the technology is specific filtering circuitry which mitigates harmonics from the load side of the device. This adds to the system's cascade effect of improved overall efficiency and improved overall power quality.

Lastly, this technology cools bulbs and ballasts, doubling their useful lifetime and dramatically reducing replacement and maintenance costs.

High Efficiency Transformers:

Approximately 6% to 12% of a facility's electric bill can be attributed to losses occurring due to lower efficiency transformers. Replacing older transformers with high efficiency ones can dramatically reduce these losses.

In fact the global electricity savings potential of switching to high efficiency transformers is estimated to be 200 TWH.

High efficiency transformers often sell at a premium but taking the full life cycle costs into consideration will very often prove the investment to be economically sound and justified.

BUILDING ENVELOPE SOLUTIONS :

A building envelope is really a system of interdependent components. Like any system, it can only function as well as the least efficient part.   The envelope includes windows, walls, roofs, and other structural components.  An energy-efficient building envelope can provide many benefits such as it reduces the mechanical system loads and lowers heating and cooling bills.

In addition, an energy-efficient building envelope is becoming more and more important due to governmental regulations and updating of building codes and mandating of higher levels of energy efficiency.

DEMAND CONTROLLED VENTILATION (DCV) :

To meet ASHRAE 62.99, most HVAC systems are designed to supply ventilated air based on assumed, rather than actual, occupancy. This often results in over-ventilation, wasting both money and energy.

The DCV control system monitors conditions in every zone, then delivers the required ventilation where it is needed.

Combination temperature/CO2 sensors allow us to design systems capable of meeting exact occupancy requirements while saving up to 20% of operating costs.

RENEWABLE ENERGY:

Achieving renewable energy goals can involve an extensive array of choices in materials and high performance technologies. Evaluation and selection of the most advantageous technologies, strategies, and materials is essential to the success of your project.

EETC has broad-based expertise and experience in renewable technologies, such as:

• Distributed photovoltaic (PV) electric generation
• Wind turbines
• Solar-thermal water heating
• Solar concentrator technology for utility-scale generation
• Micro-hydro, tidal, current, and wave conversion to electrical energy
• Storage system technology and implementation

OIL SUPPLEMENTATION FOR HERMETICALLY SEALED REFRIGERATION, COOLING AND LUBRICATION SYSTEMS:

A/C and refrigeration system loads, especially during warmer months, can dramatically increase electricity consumption and operating costs. As these systems age, they typically become less efficient as internal components wear and internal heat and pressure speed up system degradation. Efficiency is lost and maintenance becomes more common and costly as parts and even entire systems must be replaced.

The additive we utilize is the culmination of years of advanced lubricant research and testing and is specifically engineered for the severe service environments of refrigeration, air conditioning and hermetically sealed lubrication systems. It enhances the heat transfer capabilities (the "Q" factor in physics) of evaporator and condenser coils by introduction of a highly polar particle into a system's compressor oil. It gives new life to bearings, seals and compressor parts. It also molecularly bonds with the copper tubing and dislodges oil deposits and "gunk" allowing it to be removed from the system and captured by the system's filters.

The additive will not void manufacturer warranties.

This is a quick, simple, and cost effective way to lower the operating and maintenance costs of these systems resulting in increased cooling capacity, decreased electricity consumption and reduced compressor noise.

HARMONICS MITIGATION:

Advances in technology and equipment continue to reshape how electricity is consumed in today's business facilities. The continual development and introduction of more nonlinear electrical equipment has resulted in higher energy costs and the introduction of higher harmonics levels that contribute to energy waste. With more AC to DC conversion equipment, variable frequency drives (VFD), DC drives, rectified DC power systems, welders, robotics and arc lighting, harmonic current has become a more predominant and troublesome factor in modern electrical demand.

By canceling a portion of the harmonic power normally drawn by such loads, we reduce a small amount of kilowatt-hour consumption and alleviate many of the problems associated with harmful harmonics within a facility.

Harmonics are multiples of the fundamental frequency of an electrical power system. If, for example, the fundamental frequency is 60 Hz, then the 5th harmonic is five times that frequency, or 300 Hz. Likewise, the 7th harmonic is seven times the fundamental, or 420 Hz, and so on for the higher-order harmonics. If these harmonic currents flow in a power system, then they cause what is known as poor "power quality" or "dirty power". Harmonic currents cause higher RMS current and voltage in the system and cause problems such as wasted energy, overheated transformers, overheated conductors, worn conductor insulation, misfiring of AC and DC drives, tripped circuit breakers and blown fuses.

By mitigating harmonics the aforementioned problems are rectified, some electrical energy is conserved and production is no longer interrupted.

LIGHTING RETROFITS / UPGRADES:

A lighting retrofit is the practice of replacing components in the lighting system with counterparts that make it use energy more efficiently. A lighting upgrade is any strategy that reduces the system's energy use. Energy savings are realized quickly and over time and can be significant enough to not only pay for the new equipment, but produce a significant return on the investment. Typically, in a well-designed project, lighting energy costs can be reduced by 40-60 percent, and sometimes more. These savings are achieved by a combination of replacing the primary working components within light fixtures (i.e. newer energy-efficient lamps and ballasts); redesigning fixtures for a different configuration of lamps, ballasts, and reflectors; and replacing existing fixtures with new, more efficient ones. Additional savings may come from installing occupancy sensors so that lights can be automatically turned off when no one is in an area.

In addition, a lighting retrofit project can save a business on maintenance costs-both materials and labor. This is achieved through a combination of products with longer lives and/or a reduced number of components.

LIQUID PRESSURE AMPLIFICATION FOR REFRIGERATION SYSTEMS:

LPA is used to pressurize the liquid line with no temperature rise, which sub-cools the liquid, ensuring vapour-free liquid delivery to the expansion valve while condensing pressures can be reduced to allow the system to operate at higher efficiencies.

Free cooling liquid delivery pumps deliver refrigerant up to 40 times more efficiently. Reduction in head pressure and improvements in coefficient of performance can increase capacity 58%, reduce power 37% and save up 40% in energy.

ENERGY MANAGEMENT SOLUTIONS:

Our smart energy management technologies allow our customers to easily control HVAC usage and improve energy efficiency by adjusting and maintaining temperature based on occupancy, using a combination of occupancy sensors, intelligent programmable thermostats or packaged terminal air conditioner (PTAC) controllers.

POWER FACTOR CORRECTION:

Distribution losses can be a small contributor to higher energy and maintenance costs. Canceling the reactive current demanded by inductive loads such as motors and transformers reduces these losses. By treating these individual loads, a facility's electrical distribution system and equipment run better and last longer and operating costs are reduced by eliminating penalties from the utility company and slightly reducing kWh consumption.

Electric Power has two components: Active Power, measured in KW, which produces work and Reactive Power, measured in KVAR, which is needed to generate the magnetic fields required for operation of inductive loads such as motors, but performs no useful work. Total Power is measured in KVA. The ratio of Active Power to Total Power is the Power Factor. Since most Electric Utilities charge based on KWh usage, there is no direct charge for the Reactive Power used by many facilities. Active current and Reactive current both flow in the wires from the utility to the individual loads at the facility.

Significant distribution losses are present inside facilities. More current flow through the facility equates to higher distribution losses. Distribution losses in a facility can be in the following forms: Hysteresis, Skin-Effect, Proximity Effect, Transformer Losses, Line Losses and Eddy Current. Line Losses can consume 1% to 3% of a facility's overall KW usage. Hysteresis and Skin-Effect can add 1% to 5% to a facility's KW usage.

When power factor correction is accomplished at (or as close as possible to) the load, the required reactive current will only flow back and forth in the conductors connecting the load to the capacitors, thus reducing the overall current flow in the remaining facility electrical conductors. Current reduction results in a reduction of distribution losses, thus a small reduction in KWh consumption. Reducing current flow reduces the overall heat in the facility distribution system. Treating for harmonic current further reduces the amount of current flowing through the facility conductors, resulting in slightly greater reduction in distribution losses and KWh consumption.

Lastly, an added benefit of current reduction is that capacity of the facility distribution system increases and is now available to add additional electrical loads without overloading the current system or having to make a significant investment in transformers and conductors.
